HDFC Credit Card
HDFC Credit: Invalid Sur charge

I've fueled my bike and paid the payment by my HDFC C.C, as i've been told that no sur charge will be charged on any petrol payment, still I've been charged with Rs. 10 on it.

No action has been taken from the bank, after several emails, as i can not afford to go at the branch just for Rs. 10/-.

Just sheet service.
